P1131 - Lack of HO2S-11 Switch, Sensor Indicates Lean A HEGO sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time. See Possible Causes for DTC P1130

P1130 - Lack of HO2S-11 Switch, Fuel Trim at Limit The HEGO Sensor is monitored for switching. The test fails when the HO2S fails to switch due to circuit or fuel at or exceeding a calibrated limit.

  • Electrical:
    • Short to VPWR in harness or HO2S
    • Water in harness connector
    • Open/Shorted HO2S circuit
    • Corrosion or poor mating terminals and wiring
    • Damaged HO2S
    • Damaged PCM
  • Fuel System:
    • Excessive fuel pressure
    • Leaking/contaminated fuel injectors
    • Leaking fuel pressure regulator
    • Low fuel pressure or running out of fuel
    • Vapor recovery system
  • Induction System:
    • Air leaks after the MAF
    • Vacuum Leaks
    • PCV system
    • Improperly seated engine oil dipstick
  • EGR System:
    • Leaking gasket
    • Stuck EGR valve
    • Leaking diaphragm or EVR
  • Base Engine:
    • Oil overfill
    • Cam timing
    • Cylinder compression
    • Exhaust leaks before or near the HO2S(s)
A fuel control HO2S PID switching across 0.45 volt from 0.2 to 0.9 volt indicates a normal switching HO2S.

I have a 2002mercury sable, idles rough but runs good when acceleration. I changed fuel filter,plugs, plug wires, coil, still idles rough.Autozone had three codes, P0316, P1151, P1131. What should I do...

P0316 crankshaft position sensor, camshaft position sensor, or a wiring issue. Since this code indicates a start up misfire, pay attention to items which may expand or contract when cold (if the code sets when the engine is cold), or hot (if the code sets on a hot restart).

If you have other misfire codes that pertain to individual cylinders, you should attend to them first P1151 has a huge list of things that it can be, But included in that list is the camshaft position sensor , po1131 is the same thing, all building up to your car is running lean , so I'd do the sensor (cam) and check timing,,

1990 ranger 2.3L runs rough.at idle and when cruising. good acceleration. changed out the obvious, plugs, cap, filters etc. no luck. runs fine for awhile with egr sensor disconnected than reconnected, but...

There will be an egr control solenoid that allows vacuum to reach the egr solenoid, sometimes it will be called the egr vent solenoid. It is probably bad.
